Breeding Ethics
Please read the following information before purchasing a Labrador Retriever
My aim is to produce healthy, sound, unaffected puppies for a quality life.
Not all diseases have modes of inheritance, nor do all diseases have screening tests. Some are based on phenotypic evaluation, others on genetic testing.
I have all me dog's Hip and Elbowed X-rayed and Scored and DNA tested for PRA, EIC and CNM.
Currently in Australia we are able to DNA test for some known diseases such as PRA and EIC.
I have sent my CNM swabs to France as this test isn't available in Australia yet.
The results which can determine the genotype, the results can be either of the following:
Clear (A) Carrier (B) Affected (C)
CLEAR (A)- they will never develop this disease
When both parents are CLEAR they will have 100% CLEAR pups.
CARRIER (B)- they will never develop this disease
A CARRIER should only be mated to a CLEAR. This means statistically 50% of the litter maybe CLEAR and 50% CARRIERS. Testing is required of the pups. Only CLEAR pups should be selected for potential breeding and CARRIERS for pets.
AFFECTED (C) - will develop disease
50% Clear 50% Carrier

In time to come I would like to use all CLEAR within my breeding program ( PRA , EIC) and still have Labradors that look like labradors and meet the Breed Standard.
If any of my puppies are sold on Main Registration ( breeding, show potential) they must pass all genetic testing. This testing will occur at my cost and before leaving for it's new home.
All pet puppy buyers will recieve a $100 refund when a desexing certificate is produced.
I will do all my best to help and improve the health of the
Labrador Retriever

What is Hip/Elbow Dysplasia?
Good Hips
HD is a crippling congenital malformation that is caused when the ball of the thighbone does not fit properly into the socket of the hip joint.
Dogs should be X-rayed and evaluated for the condition before considered for breeding. It is recommened that your dog should have a score less than 12.13 to be used for breeding. The Radiology practice will give you a score for the left and right side that gives you a total.
Elbows are also graded between 0-3. Only scores of 0-1 should be considered for breeding. In both cases the lower the number the better.
Obesity and over exercise at a young age can increase the severity of the disease.
Progressive Retinal Atrophy (PRA)
PRA refers to a group of inherited disease that cause loss of sight. Progressive Rod Cone Degenration ( PRCD ) is a the only form of PRA disease known.

Exercise Induce Collapse (EIC)
Some Affected Labradors with EIC may seem to become weak in the rear limbs and may collapse after strenuous exercise. Some dogs may just show signs of collapse sporadically. EIC has known to be fatal.

Centronuclear Myopathy (CNM)
Affected puppies have significant weight loss . At one month of age, the absence of tendon reflexes . The age of onset of the disabling varies between 2 to 5 months, with an awkward hopping gait and a decreased exercise tolerance and generalized muscle weakness. The pup will never recover from this disabling disease. ( This is not EIC)
